New proof testosterone reason women outlive men: Study
WASHINGTON (AFP) - Scientists said on Monday they have new evidence about why women live longer than men, from a study of historical data showing castrated Koreans far outlived their non-eunuch contemporaries.
The study, published in the scientific journal Current Biology, used detailed genealogical records of the Imperial nobility during Korea's Joseon dynasty, which spanned more than 500 years from the late 1300s to the early 1900s.
According to the data, most men, including kings and royal family members, died in their late 40s or early 50s.
But noble-class eunuchs - men who were castrated either by accident or because of social benefits - lived, on average, to the ripe, old age of 70.
